IMPROVEMENT IN WATER-METERS..

Speciiication forming part of Letters Patent No. 113;@3069 datedDecember 24, 1872.

To all whom it may concern:

Be it known that I, Wnnsrnn PARK, of Norwich, in the county of NewLondon and State of Connecticut, have invented certain Improvements inTater-Meters, of which the following is a specification:

The iirst part of my invention relates to the construction of aWater-passage through the meter, opening and closing in such a mannerthat, when open, it shall be capable of deliveringqfreely the wholecapacity of the supply; and Whenl the supply is diminished the water-Wayis contracted until-when the smallest stream is running-its wholeimpulse is concentrated, through a very small opening, upon a smallmotor, only large enough to run the registerin g mechanism 5 the obj ectbeing to make the motor sensitive to the smallest iow, and to reduce thesize, expense, and friction as much as possible without impairing itscapacity to discharge freely larger or full sized streams. The secondpart of my invention relates to the combination of such mechanism andwheel-gearing as will move the indicators according to the size of thestream iiowing through the water-Way and giving motion to the motor, soas to make the first part of my invention practicable for the. accuratemeasurement of all sized streams, as the motion ofthe motor representsthe velocity of the stream, which, by the mechanism, is multiplied byits size 5 hence indicating the quantity of water.

Figure l is a top viewA of a machine embodying my invention. Fig. 2 is aside elevation of the same. Fig. 3 is a side elevation of the tlume andvalve and those parts not shown in Fig. 2. Fig. 4 is a verticaltransverse section of the flume taken in any part of its length.

The drawing shows the full size of the parts of a meter for ordinarydomestic use.

A is a chamber, into which the water flows from the supply-pipe W, andfrom which it ilows evenly into the flume B, and is discharged at theopposite end of the case, as indicated by the arrow, the case itself notbeing shown in the drawing. U is a rectangular bar or valve pivoted atS, which falls by its own weight, and is raised by therunning stream,the end of the ume conforming to the arc in which the end of the bar Cmoves. D is the Water-wheel or motor, which is preferably formed like aninverted tub, as shown in the drawing, having small iioats attached toits periphery. This gives motion to the wheel E by means of the worm L.J is the rack, secured to the bar C by the connection 0, and which, bymeans of the sector H, opens back the guard G as the valve is raised. Fis a ratchetwheel, from which, by the pinion It, motion may be given tothe ordinary indicators used in meters. V is the shaft xed upon the sideof the flume, upon which both the Wheels F E and the guard Gr allrevolve. N N is a pawl, pivoted through the wheel E, and revolving withit. One end, resting upon the guard G, through the upper part of itsrevolution, raises the other end clear of the teeth of the ratchet,except through the space that the guard G is thrown back bythe raisingof the valve, when the pawl dropsby its own weight into the teeth, andmoves the ratchetwheel more or less, according to the height of thevalve. T is a stationary guard to throw the pawl out of theLratchet-teeth, when its own \weight keeps it out through the lower partof its revolution 5 and the pawl should be provided with a stoppin toprevent its falling only just out of the teeth. M is the step, and Kisthe upper bearing of the water-wheel, and P l? are thc supports on whichthe Hume rests. U U are. one or both,bar-magnets, one attached to andrevolved by the mechanism inside; and the other following upon theoutside of the case, and moving the indicators, the case being made thinbetween them, as indicated by the line in Fig. l, so as to make theattraction as great as practicable, and each bar revolving upon a Vpointto diminish friction.

I claim as my inventionl. The automatic valve C, adjusted in the iiumeB, when so connected with the registering mechanism in a water-meter asto vary the movement of the indicators according to the opening of thevalve, for the purpose herein set forth.

2. Ilhe water-wheel D, so constructed and arranged that only the lowerstratum of water shall impinge upon it, when used to move a pawl Whoseaction is varied in proportion to the opening of an automatic valvethrough G, and ratchet-Wheel F, adapted to move the WhichtheWnterisconcentratedupouthe Wheel, indicator-wheels in proportion to thevolume as herein described. ot' water owing through a. water-meter.

3. The rack ,J and sector H, moving the WEBSTER PARK. gua-rd G inAproportion to the valve-opening, for the purpose of varying the actionof the Witnesses: paw-l. ALBERT F. PARK,
